Caveat emptor is undefeated in online shopping
Life, James Hein, Published on 11/03/2026
» It is becoming more common to buy things online. The majority of my shopping, not counting groceries, is now done that way. In the past I've warned about prices that are too good to be true, like a 4TB thumb drive for a few dollars from sites like Temu and AliExpress. There is now a kind of middle ground where the price could be correct and it's coming from, say, Amazon. Recently, even though I had some doubts, I bought a 5TB SSD drive from Amazon for around half of what I'd expect it to be. I did this knowing I can easily send things back to Amazon.
LLMs are left-leaning models
Life, James Hein, Published on 07/05/2025
» A while back I wrote about the political bias in Large Language Models (LLMs). Since then the models have evolved and David Rozado has conducted more recent tests based on four of the popular political orientation tests. Using the Political Compass, Political Spectrum, Political Correctness and Eysenck tests, he worked with xAI Grok 3 beta, Google's Gemini 2.5 pro, Deepseek V3, OpenAI GPT 4.1 and Meta's Llama 4 Maverick. In all but one of the tests Grok 3 was closest to the centre, and on average was the clear leader. All the models were still located in the Left Libertarian quadrant, with Grok just sneaking into a more Conservative area with the Eysenck test. These tests are of course but one way to measure the political leanings of any LLM. Overall however, it does still indicate the left-leaning bias in all models tested so far. If you want to see more details, you can visit David Rozado's substack.
Rise of fake AI content
Life, James Hein, Published on 23/04/2025
» We have unofficially entered the time of the fake AI generated content. It's not perfect yet, but it's good enough to fool many people. I use a YouTube alternative, which means I have more time to watch videos across a wide range. In the last few weeks, I've noticed an increase in AI generated product that is fake. One standout is the Got Talent franchise where people have grafted AI generated acts with cuts from responses from the panel. They look great, like a woman transforming into a lion, but it's all fake. Even some of those cute animal videos are now fake. Why? More clicks so more income all based on fabricated videos.
Is your internet speed too slow?
Life, James Hein, Published on 09/04/2025
» How important is a good internet connection? This is one of those how long is a piece of string or what computer should I get questions. Back in the day, it was a huge jump from zero bits per second to a 2400 Baud modem. People and businesses were willing to pay a large sum to get connected because it opened up a new world of possibilities, ranging from not needing to go to the library as often and being able to sell and market products online. When and how often you paid for the next upgrade depended on your use case and the capabilities it provided. The next major jumps in speed were 4800, 9600 and 14400bps and everyone jumped to one of these as a next step. During this period, the mid 90s, the T1 at 1.544Mbps was the imaginary godlike speed we all dreamed about but didn't have money to afford. That speed provided real time video conference calls and was limited to government and large business concerns that typically involved a dedicated screening room. This was also when the concept of data compression started to gain popularity as you could send more with less bits.
Jetsons cars finally take off
Life, James Hein, Published on 26/03/2025
» Some readers will remember the old cartoon The Jetsons. This promised a future with flying cards, robot assistants and helpful computer tools. We have or are getting very close to the robot assistants, and the latest artificial intelligence offerings seem to be the automated helpers. Missing to date are the flying cars. That may have changed with the new Jetson ONE, a single person flying car I saw a demonstration of in a recent video. It looked good, seemed to fly with good stability and landed without any issue. You can find the demos with a simple search. The craft has vertical take-off and landing capability. However, I shudder to think of what thousands of these might look like in the skies above a city without some serious improvements in driving and collision avoidance.
Do you really own your devices?
Life, James Hein, Published on 11/09/2024
» Do you own the hardware and software you purchased? Yes, no and possibly, so let's dive into an example. A man buys a second-hand Microsoft Surface from the Internet. It is one of a batch. He uses it for a few years until one day a massage pops up on the screen advising that Mastercard has locked the device and it should be returned to Mastercard. The man does some research and finds out that Microsoft has embedded some software in the firmware and BIOS that has enabled this to occur. It also turns out that this software can be found in other Microsoft and Apple devices, is very difficult to detect and requires a high skill level to remove, or you can just install Linux.
The future of AI is LAM
Life, James Hein, Published on 14/02/2024
» After my earlier article, I realised I was somewhat scant on what a Large Action Model (LAM), also called Large Agentic Models, are. As already mentioned, these have derived from the Large Language Models (LLM), or what people now refer generically as AI, discussed before.
Rabbit R1's AI action intrigues
Life, James Hein, Published on 31/01/2024
» A new device out of CES 2024 in Las Vegas caught my eye. At first glance, the Rabbit R1 doesn't look all that interesting. It's a US$199 (in America), orange, handheld device that looks like an old-style gaming machine of some kind about the size of a stack of Post-It notes. It comes with a 2.88-inch touchscreen, a camera, a voice command button and a 4G LTE SIM card slot for connectivity beyond Wi-Fi. This is not a smartphone and won't replace it as there are no onboard apps, it won't pair with your smartphone and it doesn't talk to application APIs like cloud service gateways.
Graphene semiconductors mark new start
Life, James Hein, Published on 17/01/2024
» We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.
7 levels of AI await humanity
Life, James Hein, Published on 02/08/2023
» This week is AI week, both to date and going forward. Some don't understand the difference between AI and AGI, the latter being artificial general intelligence, denoting a system that behaves like a human being in capabilities. So, for your amusement I've put together, with credit to the YouTube channel AI Uncovered, a description of the seven levels of AI.
